Unformatted text preview: T m + 50 K . How does the error from this temperature compare to that in part e)? (5 points) The following data is given for aluminum: T m = 660 C h m ( ) T m = 10 , 500 250 J mole-1 c P ( ) solid = 20.67 + 12.38 10 3 ( ) T J mole-1 K-1 c P ( ) liquid = 31 . 76 J mole-1 K-1 2) (10 points) The molar volumes of solid lead and liquid lead at the melting temperature of lead (600 K) are, respectively, 18.92 cm 3 and 19.47 cm 3 . Assume that these molar volumes are independent of pressure. Calculate the pressure that must be applied in order to raise the melting temperature to 625 K. The enthalpy of melting of lead at 600 K is 4,810 J/mole....
